☣️ THE ONLY LOGICAL APPROACH TO A ZOMBIE PANDEMIC ☣️

[hr][/hr]

Obviously, the logical solution to a zombie apocalypse is to set up a full laboratory in your backyard and start poking around in contaminated blood.

Build questionable equipment, perform autopsies with dubiously sourced tools, synthesize compounds that probably shouldn't be anywhere near fire, and try to develop a cure before your closest volunteer decides to take a bite out of you.

You can set up a workbench, melt glass for tubes and flasks, process infected blood, extract leukocytes and antibodies, and—with a bit of luck—synthesize vaccines or maybe even a cure.

📚 Oh, and about the textbooks… Your virology books aren't exactly lying around in Grandma's living room.

They're probably in military research sites, St. Peregrin Hospital and the Louisville university lab — you know, those charming places with armed checkpoints, biohazard warnings, and approximately eight million zombies per square meter.

If you want to learn, you'll have to earn it. And by "earn it," I mean "run for your life while clutching a book like it's a family heirloom." 🏃

Good luck. You're gonna need it. ☠️ [hr][/hr] The idea of this mod is not to give you a free pass to ignore infection. It doesn’t remove the fear of death. Instead, it gives you a long-term goal — a chance to develop something that might save you.

Until you reach that point, survival still comes first. You’ll need to stay alive, stay healthy, and manage your resources carefully. Research takes time, preparation, and risk. It means you can — and probably will — die in the process if you’re not careful.

This is a complex system designed for players who want to dive deep into scientific research and experimentation.

Features:

✅ Custom laboratory equipment that works as vanilla-like workstations; ✅ Unique research items; ✅ A full vaccine and cure development system — for you to die trying; ✅ Progressive research mechanics: from performing autopsies to collect blood samples and infected brains, to even extracting human bones to assemble a full anatomical model; ✅ Rare research books and technical manuals that unlock procedures most survivors wouldn’t even dare to attempt; ✅ Blood testing system — now you’ll know if that scratch just put an expiration date on you; ✅ Dynamic experience system influenced by profession, perks, and sample results...

...and more to discover the hard way.

🔬 COMES WITH RESEARCH LABORATORY INTERN PROFESSION Starts with virus research documents stolen from a university lab after realizing the guy in charge kept disappearing with the military.

F.A.Q:

Can I safely add it to an existing save/world server? Yes, you can. But loot will only spawn in unvisited areas.

Can I safely remove it from an existing save/world server? Nope. Due to how the game handles workstations, it's not safe to remove the mod from an existing save.

Does it work with mod X? Probably. This mod doesn't change core systems of the game and runs independently, therefore it should run fine along with other mods. I have other 50 mods enabled and have no problems so far. Someone in the comments said he tested alongsied with other 500 mods ☠️ and it worked (dude is just nuts).

known incompatibilities: - zReVaccine.
